Measurement of the Quasi-Two-Body B Decays

Abstract

We study the contributions of the $B\rightarrow \psi(3770)K[\psi(3770)\rightarrow D\bar{D}]$, $B\rightarrow K^*(1410)\pi[K^*(1410)\rightarrow K\pi]$ and $B\rightarrow X(3872)K[X(3872)\rightarrow J/\psi\gamma, \psi(2S)\gamma, D\bar{D}\pi, J/\psi\omega, J/\psi\pi\pi$ and $D\bar{D}^*\pi]$ quasi-two-body decays. There are no existing previous measurement of the three-body branching fractions for three final states of the $X(3872)\rightarrow J/\psi\gamma$, $\psi(2S)\gamma$ and $D\bar{D}\pi$ but several quasi-two-body modes that can decay to this final state have been seen.
